'AppHcationfiledMay22, 1922. Serial imise2ea To allwhom it'm ay concernt Be it'known that 1, LEE W.DUNCAN,"11

citizen of theUnited States, residing at Fort XVayne inthe county of-Al'len and State of Indiana, have invented certain new'andusee' ful Improvements inW-indow Protectors, off which the following isa specification. 7

My invention, has reference, 1 in v general terms, to devices for reinforcing and preventlng' unduevibration of window glass and thelike, more particularly it -is-designed for'minimizing or absorbing either sudden shocks or prolongedstress-and strain through theexertion of sustained and com 7 provide a resilient, sustained reinforcement" bined' cushioning and suction the glass plate or pane.

High and blustering ction' upon winds both I exert pressure and create partial vacuums which" cause variable outward and inward stresses upon window glass and consequently a prot tective device to be efit'ective, must exert a sustained and elastic action both against outward and inward movement of the glass;-

A device whichserves as a fixed stop against inward movement only (caused by pressure of high winds) has a tendency to cause more damage than otherwise, as glass will rebound against it. Furthermore, a certain amount of give is desirable, and to this end a device of this charactershould exert a sustained and elastic cushioning effect rather than be a fixed, comparatively.non resisting stop. a

With the foregoing objects, which briefly stated, are: first, to

in the form of a suction cushion for minimizing outward and inward shocks upona window glass or pane; second, to provide a device which may be quickly applied to any window pane either as a permanent fixture or as a temporaryv appliance for use in a special emergency; third, to provide means for quickly adjusting the device to exert a varying amount of pressure; 'and,fourth, to

attain the foregoing objects and others of equal importance, with a simple and inexpensive device which may be'manufactured and placed on the market at small cost, and which may be applied,,or the parts intertion, and

in view, my invention is designed to attain the following principal To these i and other ends, invention. consists in the construction, arrangement.

It 1" will be seen that adjustment of the shank} It is here pointed out that a plurality of rubber vacuum cups may be useth either by arranging them in groups or by providing openings in the T-portion of the'shank (3).

In operation the cup (7) exerts both a. cushioning and a suction effect upon the -.glass thereby stabilizing and reinforcing the glass both against inward and outward pressure.v The device may be quickly mounted or detached, or swung toan position by removing all but one of the bolts(2), and the vacuum cup may be read-i ily withdrawn from the glass by operating the thumb-nut Parts which become worn orbroken can be replaced without special skill or tools.

WVhile in the foregoing, there has been illustrated and described such combination and arrangement of elements as constitute the preferred embodiment of my invention, it is nevertheless desired toemphasize the inoperative carried by the shank, and means arranged onjtheishank between the end of the support and the resilient pane engaging means for. adjusting the position of the shank with respect to the support whereby to adjustthe pressure of theresilient means upon the pane of glass. 7 i

2, A window protector comprising a sup port formed with anopening in one ofits ends, a screw-threaded shank adapted for slidable and removable engagement within the opening,.resilient means for engaging a pane of glass carried by the shank, and a nut arranged on the shank between the end ofthe support and the resilient. pane engaging means for adjusting theposition of the shank withrespect to thesupport where byto adjust the pressure of the resilient means upon the pane of glass.

In testimony whereof, I affix my signature hereto.
